Subject: [RFC PATCH 0/4] riscv: Add basic percpu operations
Date: Mon,  8 Aug 2022 04:05:56 -0400	[thread overview]
Message-ID: <20220808080600.3346843-1-guoren@kernel.org> (raw)

From: Guo Ren <guoren@linux.alibaba.com>

The series try to add basic percpu operations for riscv. HAVE_CMPXCHG_LOCAL
would let people confuse with cmpxchg(64)_local, so make the name more
accurate (HAVE_CMPXCHG_PERCPU_BYTE). Last, remove RISC-V's
cmpxchg(64)_local definition because it's no use.

Guo Ren (4):
  vmstat: percpu: Rename HAVE_CMPXCHG_LOCAL to HAVE_CMPXCHG_PERCPU_BYTE
  arm64: percpu: Use generic PERCPU_RW_OPS
  riscv: percpu: Implement this_cpu operations
  riscv: cmpxchg: Remove unused cmpxchg(64)_local
